Property search and valuation site Zillow expanded its suite of mobile applications today with the launch of an app for Research in Motion’s BlackBerry smartphones.

Zillow also has apps that run on Apple’s iPhone and iPad devices and on smartphones and tablets that run on Google’s Android platform. The launch of the BlackBerry app means that Zillow is now accessible for more than 90 percent of smartphone users, the company said.

According to the latest figures from comScore, 30.4 percent of smartphone users have BlackBerrys, a bigger share than those who have iPhones. That figure has been steadily declining, however, ceding market share largely to Google’s Android.

"Many of our fans — including significant numbers of real estate professionals — have asked us to bring our … mobile experience to the BlackBerry platform, and we’re thrilled to give them this option," said Spencer Rascoff, Zillow’s CEO, in a statement.
